Asset Operation

Pöyry supports the continued operation of nuclear assets through many successful longterm relationships.

Pöyry recognises that during operation of nuclear power plants and facilities there will be a need for justification of continued operation, plant modifications and operational changes driven by both regulatory, environmental and commercial requirements.

Pöyry's experience in support of asset operation is wide ranging from the design of plant upgrades to the safety justification of plant operation beyond their current licensed period. Our experience covers nuclear power plants and research reactors as well as research, fuel cycle and waste management facilities.

Various techniques have been utilised to support power upgrades and to optimise plant maintenance and operational management. These techniques have included Probabilistic Safety Assessment and the development of risk management tools. Our design capability utilises the latest 3D CAD packages.

Pöyry has developed many long-term relationships to support the continued operation of nuclear assets providing innovative solutions to difficult problems.
